Abstract

Provided is a transmission method which can effectively use a frequency band and reduce lowering of transmission efficiency caused by interference. A DFT unit (12) converts a modulation digital signal into a spectrum of a frequency band. A reception device includes a use frequency band report unit which reports a use frequency band to a transmission device (1). The transmission device (1) has a delete unit (141) which deletes a spectrum of bands other than the use frequency band after a rectification unit (13) has shaped a spectrum waveform according to the water filling theorem. A synthesis unit (16) combines digital signals of respective data sequences relating to the spectrum after the deletion by the delete unit (141). The transmission device (1) transmits the combined signals to the reception device. The reception device includes a reception side conversion unit which converts the digital signals transmitted by the transmission unit to a spectrum of the frequency band. Lastly, a turbo equalization unit turbo-equalizes the converted spectrum.
